Application filed November 11, 19537.'

This invention relates to a new and use-` ful device in the nature of an ore grading machine especially adapted for the purpose of grading in classifying ore accordingto the varioussizes ofthe said ore, which 1s more fully set forth and described in detail.

Fig. l is a side elevational view of my improved `ore grading machine.

i Fig. 2is atop plan view there-of. I

Fig.' 3:'is an enlarged detail view of the adjustable gate as embodied in my improved Fig. 4 is a top plan view ofthe adjustable screen shutter as embodied 1n. my improved idevice.

lfig. 5 isa longitudinal Jsectional view taken on the line 54-5 of Fig. 4.

lfig;v 6 is atransverse sectional view taken on the line G-6 of Fig. 4.

its here embodied my improved ore grad ing belts l0 and ll, extended over` suitable i vsprocket wheels 1:2, 13,14 and l5 respectively,secured to the shafts 1,6 and l?.` Brackets ll, or scoops secured to the said link belts l() and 1l, "are extended transversely therefrom. The shaft 1G .is rotatively mouiiited in suitable bearings 18 and 19, mounted on the upright members 20 and 2l, secured to and extended from the hopper 22, of box like construction. rlhe shaft 17, is rotatively mounted in suitable bearings 23 and 24, mounted on the upright members 25 and 2G, which .may be of any desired length or height, and which are secured, at their lower extremities to the base members 27 and 28, which are also secured to the hopper 22. f3upporting,` members 29 and 30, are secured at their upper extremities to the top of the upright members 25 and 26, and are angularly disposed downwardly therefrom, and are secured at their lower extended extremities to the base members 27 and 28.

The hopper 3l is mounted on the upper portion the Supporting members and 22to be conveyed into `lower extremity of the shaft 46.

machine comprises a link belt conveyor, `described construction is such as hereinafter set forth.

80, and is positioned partially below the sprockets 13V and l5.

Thefbevel gear 32, is secured to the shaft 17 and meshes with av bevel gear 33, secured to the shaft 34, rotatively mounted in the bearings `and 36, secured to the upright member 26. y

The above described construction is such as will permit the ore placed in the hopper the hopperl 3l when the shaft 34 is rotated by any desired means, profe ably by an electric motor operatively connected to the shaft 34 The hopper 3l, is provided with an open lower end, adapted to receive the gate'l',

of suitable `size to close the said lower end ofthe hopper 3l. rlhe gate 37, is pivotally secured as at 38, by a pin or the like, carried in the lug element `39 of the side of the hopper 3l, and is provided with a segment gear 40, adapted to mesh with the gear 4l, secured to the shaft 42, rotatively mounted v.in the brackets 43, secured to the hopper 31.

rllhe bevel gear" 44, is secured to the shaft 42, and meshes with the bevel pinion 45, secured; to the shaft 46, rotatively mounted inthe bracket 47, secured to the hopper 3l, and inthe bracket 48 secured to the member 49. The hand wheel 50 is secured to the The above will permit the gate 37 to be pivotally opened by rotat ing the hand wheel 50, as designated by the reference"numeral 51, for the purpose as A plurality of screens 52, aresecured to the supporting members 29 and 30, the said screens 52, being of conuaaratively heavy wire mesh, so as to providev the desired rigidity, and are of various mesh, the upper or top screen beingof comparatively tine mesh, the lower screen being of coarse mesh, the intermediate screens being graded, as regards the mesh thereof.

Side members 53 and 54, are secured to the supporting members 29 and 30. and es;A tend from the hopper 31, into proximity to the lower extremities of the said supporting members. Partitions 55 extend from the upper and lower extremities of the screen 52, downwardly therefrom and are secured to the base members 27 and 28, side members 56 and 57, being secured to the lower extended extremities of the partitions 55, as a means of providing bins, or compartments ander the said The .above de l scribed construction is such as will permit ment teeth 60, adapted to mesh with the gear (Sl, secured to the shafts G2, VArotatively mounted yin the brackets 63, secured to' the side members 58.. The vhand wheels 64, are

secured to the lower extendedV extremities oi. the shafts 62. `The side member 58, has

" formed thereinV elongated openings adapted above described construction is such as will to slidably engage the shutters 58. The

permit the shutters 58, to be pivotally extended, as may be desired, partially over the screens 52, as a means of limiting the useulness et the said screens 52, as is desirable for ores of various sizes, which do not require the whole amountot screening as is provided,

. and Iwhich will increase the rate ot grading of the saidjore.

Expansion springs 71 and 72, are secured `to the brackets 73v and 74, respectively, at-

tached to 'the side member 53, and are posif tioned in the cup members 75 .and TG, respectively. The'cup members 75 and 76,; have Yformed therein, elongated aperturesv77 and 78, respectively, adapted to receive the screws '7 9 and 80, as a. means of slidably attaching the cup members 7 5 and 76, to the side member 53. The above described construction is suchv as will permit the springs 7l and 72, to hold the shutters 58 in engagement or in contact with the screens 5 2, lasa means of preventing particles ot the ore which may lodge on the screens 52 from interfering with lthe movement of the said shutters 58.

Extended members G5, are hinged as at 6G,

tothe inner edge of the shutters 58. The thumb screws 66, are threadedly mounted in the side member 53. The tension springs 67, are secured to the thumb screws 6G, and to the lug elements 68 of the extended incinbers 65. The above described construction is such as will permit the extended members 65, to be raised in a vertical position as designated by the reference numeral 69 when the shutters 58, are extended over the screens 52, as designated by the reference numeral 70.

lThe above described construction is such as will prevent the ore from falling or rolling over the shutters 58, when in an extended position. I

Having thus described my invention, what I claim as new and desire to protect by Letters Patent of the United States is as follows: f

1. In a device of the class described, a screen, a shutter adapted for manual operan tion, and extended member hinged to the inner edge of the shutter, and a means for elevating said member when the shutter is projected over the screen. n l

r2. In adevice of the class described, a screen, a shutter adapted for manual operation, an extended member hinged to the inner edge ot the shutter, a lug element projecting therefrom, a tension spring attached to the lug element and arranged for elevating the sa'id member when the shutter is piojccted over the screen.

3. In a device of the class described, a

screen, a. shutter adapted for manual operation, an extended member hinged to the inner edge of the shutter, a. means for holding the shutter in contact with the screen, a lug element projecting tllcrefrom, a tension spring attached to the lug element und arrangd for elevating the said member when the shutter is projected over the screen.

, In testimony whereof I have alixed my signature.
